PORT'ABLE BASKET-GRATE.

SPECIFICATION forming part of Letters Patent No. 324,102, dated August11 1885.

Application filed April 18, 1884.

To all whom it may concern:

Be it known that we, HENRY FRIEDRICH, of Port Chester, inthe county ofWestchester and State of New York, and CHARLES WV. CARSON, of the sameplace, have invented an Improvement in Portable Basket-Grates, of whichthe following is a specification.

Basket grates for fire-places have been made of a configurationresembling our device, but they are constructed in a different manner.

Our improvement relates to the joints by which the parts are puttogether, so that the expense of construction is lessened and thebasket-grate increased in strength.

In the drawings, Figure 1 is an elevation of the grate. Fig. 2 is a planof the grate partly in section. Fig. 3 is a section of one of the logs.Fig. 4 is a view of part of the back.

Fig. 5 is a section at the line w .70, Fig. 1.

The grateframe a is usually wider at the front than the back. The gratebissupported upon trunnions 0, so as to be dropped for emptying the fuel.

The legs supporting the grate-frame have heretofore been cast in onepiece with such frame, and to allow for drawing the pattern out of thesand they have been simply plain and tapering.

To have improved upon the legs by casting them separately from thegrate-frame, each leg 6 being more or less ornamental, and preferablyprovided with a roller, f, at the bottom, so that the basket-grate canbe rolled back and forth in the fire-place. At the top of each leg thereis a dowel, 7;, having a pcripheral groove, and the dowel is preferablyoblong, so as to insure the proper placing of the leg in the patternprevious to the molding of the grate-frame pattern in the sand. Alterthe grate-frame pattern is removed the iron is cast into the mold andruns around the dowels of the respective legs and holds them permanentlyto the leg-frames.

It is important that the front bars, Z, of the basket be smooth andparallel, so as to be ground off and polished on tlie top and frontsurfaces. YVe cast such bars, and either cast or bore holes for thebolts 0,that pass through the bars 1, the intermediate ornaments m, and

through the grate-frame a. These bolts 0 are provided with nuts at theirlower ends, the heads usually being countersunk in the top bar, Z, andground off, except where there is a top ornament, n, in which case suchornament forms the head for the screw-bolts 0.

Upon the surfaces of the grate-framea,near their ends, there aredovetail ribs 19, and the end pieces, q, of the grate are cast withdovetailed lower ends,to be slipped in between the dovetail ribs 1) fromthe inner part of the grateframe, so that said ends are held in theirplaces.

The dovetail is tightened by any pressure of coal within thebasket-grate.

In the vertical inner faces of the end pieces, q, there are notches orgrooves, as shown at 5 in the plan view, Fig. 2, and the back plate,r,is of a size to slide vertically into such grooves, and at the topcorners of the back there are downward projections or hooks s, that passoutside the upper edges of the end pieces, q, so as to prevent such endsspreading by the pressure of the fuel within this basket-grate.

Usually the back plate will be ornamented with raised figures and nothave any holes or openings through it.

The basket-grate made in this manner is cheap to construct and verystrong, and the front bars can be ground and polished off, so as to behighly ornamental.

The legs may be cast in any desired manner and with or without therollers; but they are to be completed before the dowels at the upperends are placed in the pattern, because sueh legs can be more easilyfitted with the rollers when separate from the grateframe,

We claim as our invention- 1. In a portable basketgrate, the legs forthe grate-frame having dowels at their upper ends, and the grate-framecast around such dowels and holding said legs, and dovetailed lugs uponthe surface of the grate-frame, in combination with the end pieces,q, ofthe hasket-grate having dovetailed projections fitting between suchlugs, the bars Z, intermediate ornaments m, and screws 0, substantiallyas set forth.

2. The end pieces, q, having notches upon Signed by us this 31st day ofMarch, A. D. their inner faces, in combination with the back 1884.

plate, 0', passing vertically into such notches,

and having hook s passing down outside the 5 end pieces, and thegrate-frame a, to which Witnesses:
